BASIC MATH OPERATIONS

Your calculator uses standard chaining logic which simply means that you enter your first value, the operator ( + , – , x ,

÷ ), the second value and then the equals sign ( = ).

3 + 2 = 5

3 – 2 = 1

3 x 2 = 6

3 ÷ 2 = 1.5

This feature also makes the calculator simple to use for dimensional math.

Adding or Subtracting Dimensions

1) You can add or subtract two numbers when the first value entered is labeled with units of measurement and the other is just a whole number (no units of measurement).

2) You can add or subtract numbers whose units of measurement are within the same convention. For example, you can add or subtract kg and pounds.

3) You cannot add or subtract two numbers of different conventions, except for weight and volume.

4) The format of the first value you enter determines the format of the answer.

However, you can use the Ç key to change to any format desired, provided that you maintain convention.

Examples:

5. Subtract 32 mm from 8 centimeters:

8 c – 3 2 M = 4.8

Multiplying or Dividing Dimensions

1) You can multiply and divide two numbers when the first value entered is labeled with units of measurement and the other is just a whole number (no units of measurement).

2) You cannot multiply or divide two numbers that have different units of measurement or different conventions, except for weight and volume.

3) You can multiply and divide numbers when their units of measurement are within or between the linear and area conventions. For example, you can multiply kilometers by square feet, which will give you cubic kilometers.

4) The format of the first value you enter determines the format of the answer.

However, with the Ç key you can change to any format you desire, provided that you maintain convention.

1. Multiply 5 feet 3 inches by 8 feet 6-1/2 inches:
